Real-Time Aurora Activity

Check the chance of seeing the northern or southern lights from your location.

Auroras are atmospheric glows driven by solar particles and Earth’s magnetic field. This page estimates current activity from real-time space-weather data.

Your coordinates: Latitude: 37.3541°, Longitude: -121.955°

Aurora probability now: 0%

Visibility status: Very low probability of aurora visibility. Likely no aurora.

Solar wind conditions

Solar wind speed: 507.7 km/s

Solar wind density: 0.10 protons/cm³

Bz component (IMF Z-axis): 1.49 nT (Northward)

Last update: 2026-06-29 03:52

Negative Bz points southward and generally allows solar-wind energy to couple more effectively with Earth’s magnetic field. Positive Bz points northward and usually reduces this transfer.

Global Kp index forecast (21 June 2026 – 1 July 2026)

The Kp index measures geomagnetic activity from 0 (quiet) to 9 (extreme storm). The chart combines observations and forecast values for 21 June 2026 at 15:00 — 1 July 2026 at 15:00.

Bz (IMF component)

Bz describes the north–south orientation of the interplanetary magnetic field. Sustained negative values can favor geomagnetic storms and auroras.
